Composition and classification of high-voltage wiring harnesses for new energy vehicles

New energy vehicle wiring harness is the assembly of the vehicle power and signal transmission distribution system. The wiring harness is mainly composed of wires, terminals, connectors, and protective sheaths; Wire harness production and processing require checking whether the wire harness is connected, short circuited, etc. Key points for processing wire harness number tubes for new energy vehicles: clear printing and consistent direction.
New energy vehicle wiring harness processing equipment includes: large square servo crimping machine (welding machine), high-voltage wire intelligent integrated machine, number tube automatic cutting and marking machine, fully automatic crimping terminal threading number tube machine, and multi-functional high-voltage wire fully automatic production line.
Electric vehicle high-voltage harness is an integrated cable harness that connects the high-voltage battery and electric drive system of an electric vehicle. It generally includes the following categories:
1. Power harness: Connect the power harness between the high-voltage battery of the electric vehicle and the electric drive system.
2. Charging harness: Connect the charging port of the electric vehicle to the charging harness of the high-voltage battery of the electric vehicle.
3. Drive harness: Connect the drive harness between the electric vehicle drive motor and the electric drive system.
4. Control harness: Connect the control harness of the main controller, electric drive system, and high-voltage battery of the electric vehicle.
5. Sensor wiring harness: Connect various sensors of electric vehicles with the sensor wiring harness of the main controller of electric vehicles.
6. Lighting harness: Connect various lights such as electric vehicle headlights, taillights, turn signals, etc. to the lighting harness of the electric vehicle main controller.
7. Instrument harness: Connect the instrument harness of the electric vehicle to the main controller of the electric vehicle.
These high-voltage wiring harnesses must use cables with high voltage resistance and high current carrying capacity, as well as waterproof, dustproof, heat-resistant and other properties. Due to the much more complex electrical system of electric vehicles compared to gasoline vehicles, designing and manufacturing high-voltage wiring harnesses is one of the important aspects of electric vehicle manufacturing.
